Catchy title! But it's mostly true! There's a pinned comment you might want to read, as well. But there's some links down here, too.
Firstly and of supreme importance, the video on the Bolt's Bits from Weber Auto - Prof. John Kelly is amazing and you really ought to give that channel a look if you're interested at all in hybrid and EV tech;

  • Hi! There are probably a few things you could be asking in regards to this video. For one, why am I talking as if an electric future is definitely happening? Well, sales of EVs are continuously growing thanks in no small part to Tesla, and I believe that the personal transportation market fundamentally needs to shift to EVs if it is to remain sustainable and practical for the future. That said, switching every car out there to electric isn’t going to solve all our problems by any means and a good, hard, critical look at car-centric policy is certainly needed. But with that belief in mind, there’s a lot of information regarding electric cars that is… confusing. Unless you’ve got experience with one or have done a lot of research, you might not have known that standard charging protocols do in fact exist. I’ve seen many comments across the interwebs from folks who say things like “I’m not willing to look at an EV until there’s a unified charging standard” and, well, those comments are a little depressing to me. As we head further into this decade, that unification of standards has happened for every automaker who isn’t Tesla, and I want to draw attention to that because as we reach this juncture, Tesla may end up harming adoption by continuing to use their proprietary connector. They have clear incentives to do it - they’re the only automaker so far that has committed to building their own fueling infrastructure. But I am immensely skeptical of a future where ever car company has made you beholden to them for fuel, which is essentially what the Supercharger network perpetuates. As more and more vehicles with the CCS combo connector come online, growth in CCS stations will occur and they’ll be run by all sorts of companies, and supply fuel to all sorts of cars. That’s really the future I think is best for consumers, and I hope that Tesla joins it soon.

    • @Jeremy Subasic - You are correct, but it doesn't cut it much. If you do a complete systems analysis from combustion to tire patch, an EV has about the same overall thermal efficiency as an ICE car, and that's between 10% and 20%.

    • Oh man again with this?.. Alec @Technology Connections .. Let's not even start with the fact, that where you see a car, I see a mountain of wasted (very scarce) lithium.. and a mountain of cell phones, laptops, and other equipment that really need Lithium. And that in the not too distant future they will no longer have it because we are dumping tons of it on this nonsense. (but Ramdileo you can RECYCLED IT) .. yes part of it.. and you use "Petroleum" and its derivatives for do that.. and then you get back a big chunk of the pollution that you saved using those batteries.. (you have the other part in the production and use of the device) laws of physics my friend... But .. Let's talk about something else "electric production.. less than efficient??!!" yea it is right? it sucks.. But do you really think that if is there a more efficient way.. or cheaper.. those filthy greedy old men.. Mr. Burns kind of disgusting dude... if is there really a better way to scratch a measly single penny .. they wouldn't use it?? (But Ramdileo.. you you can throw a SOLAR PANEL in the middle of nowhere and it will run forever) Of course not!!! (But Ramdileo.. those who are in the satellites WORK FOREVER) yes but they are in an environment of -250 degrees.. and where nothing touches them.... here you have high temperature.. you have pressure.. you have sand.. you have wind.. you have rain.. you have birds that shit on them... and etc etc etc etc... Aaaand because solar panel's are so highly inefficient at their task.. is not even worth the resources spent on its maintenance... ADD to that the resources spent on his own production (again scarce materials in comparison with other methods) ... and ADD everything else you need around them to make them work... And you see why we still use the Hoover Dam...

    • @Technology Connections You can absolutely get NC switching modules for contactors. As much as anything, it's the modularity that makes something a contactor instead of a plain relay, but theoretically, of course they're the same thing.

Your title is basically a argument about semantics. Almost 100% of people who use a device that takes power from a wall, or GRID and transfers it to a portable power supple, IS GOING TO CALL IT A CHARGER. I mean, even you do thru out this whole video.

  • Great video. Please bear in mind that you have a audience outside the US. There are already vehicle to grid systems using CHADEMO in the UK and Japan (to my knowledge). The colour (color) code cable is a European Union standard (Siemans charger). In the UK we have a charger (intelligent wall switch ;-) called zippy that matches the charging rate to solar panel output. How does that work? (maybe it modulates the 1khz square wave). I don't mean to snipe, this was a great video which covered some things I'd been curious about so keep up the good work (Mick in London UK)

  • Pedant! All batteries need charging. The electricity starts out as AC and is converted to DC which is what a battery needs! You can have a domestic 13A or 30A 240V supply or an industrial 3 phase supply. The problem is you need a cable to connect the source to the car and its needs to be connected for a long time. You spent £105,000 on a Tesla and then can't drive it for several hours while it charges. Its an expensive inconvenient toy for champaign socialists who virtue signal to their wealthy friends.

  • Tesla’s supercharger network has the advantage in that you just plug in your car and it starts charging. Also you can road trip easily in a Tesla. With the others only the connector is standardized. Some have monthly membership fees, all have their own app that you have to signup with and most don’t take credit cards at the “pump”. Then there’s the whole charge by the minute nonsense that some companies do.

  • The CCS standard was formed in 2012 with the 1st public EVSE coming online in 2013. Long after Tesla had their standard out. Europe is standardized on CCS-2 which is slightly different than the North American CCS-1 standard. Currently the CCS-3 standard is going through the pipe.

  • Great video! Not all EVSE are created equal and some of them can be much more than a "dumb switch". It should be mentioned that some EVSE suppliers have easy solutions for load balancing the main fuse of residential homes. This can be a huge boon for homes that have limited excess capacity and would otherwise struggle to have enough to go around during peak hours of the day. These homes would then be constrained to a low amp circuit or face huge costs to upgrade their main intake. The company I work for describes this in more detail on the following link: www.defa.com/what-is-full-dynamic-load-balancing/

  • A big reason for the cost of electric chargers is the precision needed for safety. If anything breaks, it could kill a car, a house, or people so tolerances have to be tiny and build quality has to be extremely good. They are also in the early stages of this product... news coverage about chargers causing problems could be catastrophic for the electric car industry. The only option is to suck it up, pay more to have things made, and take things slow and steady.

  • Fun Bolt anecdote: I bought a Bolt that appears nearly identical to your parents' in October 2017 in Omaha, NE. I planned to buy a Level 2 EVSE, and did so after a trip to Lincoln (~120 miles round trip) for Halloween meant taking 3-4 nights to completely return to full charge using the basic Level 1 EVSE that came with the car (I still had a ~50 mile round trip daily commute). Since I didn't have a 240V outlet in my garage, I also planned to hire an electrician to install one. However, once back to fully charged, I found that the Level 1 was adequately handling my daily commute with an overnight charge. I figured this wouldn't last once it turned cold, but held off on calling the electrician as a sort of informal experiment. My car just turned 3 years old and the JucieBox is still sitting in the box. I haven't *always* fully recharged overnight, but the Bolt has enough range that I've never had serious range issues when driving locally, even when I forget to plug in. As a matter of fact, the only time I've used a level 2 EVSE was when I drove to Kansas City for a family reunion. I specifically picked a hotel with one, which was fortunate because I was down to 30 miles of range when I got there. Due to bad planning, I also had to use one to add some miles on the trip back, but I treated my niece & mom (who were my passengers for the trip) to a movie while we let it charge. Otherwise, I've only ever needed the lowly 120 V Level 1 EVSE. For the record, while winters are marginally milder in Omaha when compared to Chicagoland, we still get the sub-zero temps, ice & snow. Omaha is also in about the only hilly area of Nebraska. I also have no viable charging options where I work, so I've just gotten used to operating on the assumption that any charging I'm going to do will be at home.

  • I have a Volt and a Tesla. Instead of a EVSE, I use a 240v outlet. With adapters, I can charge either car efficiently, 10m/hr for the Volt, and 22m/hr for the Tesla. The 30A breaker, the #10 cable, and the 240v outlet totaled around $40 total. The Tesla adapter was around $45, and the DIY adapter for the Volt cost around $6 or so. I hooked it up in a couple hours with basic skills. Before I installed this 240v outlet 2 yrs ago, instead of 5 hrs for the Volt, a full charge took 13hrs. EVSE may need an electrician and permit etc, too much trouble. Saving money is not the purpose, but getting it done myself efficiently gives me great satisfaction (without being mansplained and overcharged by the electrician).

  • Backfeeding will probably never be a thing, unless we learn how to make way more durable batteries. It doesn't make sense wasting charge cycles od moving batteries. And, when EV gets bigger market share, we will have supply of little bit degraded batteries which are not suitable for high range cars anymore, but perfectly good for stationary power storage.

    • @Jim Michaels also, when today EVs get older, old EV battery with capacity drop of 25% will still be more than usable for that purpose.

      MrBlcMrBlc7 päivää sitten
    • Absolutely, why would you add extra unusable battery capacity and an inverter function to an EV for the occasional use by the grid. The added cost, weight, space, maintenace, compexity, etc. would provide no benefit to the EV and many serious negatives. The same Grid share battery capacity could be added to the EVSE for a fraction of the cost of building it into the Vehicle and it would be available to the grid 24/7. With Peak Metering It potentially could provide some cost savings for the consumer. Another possibility is faster charging in situations where utility power capability is less than vehicle on-board charger capbility ( example 30amp 240V circuit and EV with 7.2kW Charger which would normally be limited to 5.76kW charging)

  • Charge 16 cars at once? That's so 2015 :-) I have overseen projects to charge 400+ cars, using WiFi to balance the load. Each car can charge 22 kW, but the total load is balanced to protect the main fuse. The chargers can communicate with the car and read its serial number, battery status etc. according to ISO15118. You don’t even need to identify yourself; the charger recognizes the car.

  • Could you just put a wall plug on the charge cable and leave the evse out? let the charger do the work?

    • The Car needs to know from an EVSE if its clear to draw power and most importantly: How much. Lest it try to burn your house down by drawing more power than your grid can handle... This is where Charging cables with a In-Cable Control Box come in (aka "Granny cables"). Which you can use to plug your car into a generic wall-socket. In various places Granny Cables are a standard pre-included accessory with new cars. Just don't expect it to charge quickly and keep in mind that they won't charge remotely fast. They are more an in-case of emergency (broken Wall-box, charge-card or just being somewhere with no charging stations). ~signed. An EVSE Engineer.

  • In California, electricity is a scarce commodity. We have rolling blackouts due to inadequate power grids and overpopulation. Our Governor has signed a bill calling an end to the sales of petroleum powered vehicles. Only electric vehicles will be sold here at some point. I wonder how we are going to charge them... You could call an electric powered car a coal powered car, as that is how the bulk of our electricity is made. Windmills, in their lifespan, will not generate enough electricity to even pay for themselves. The only reason they exist is because of government subsides. Now let's talk about the carbon footprint of an electric car...

    • The power grid my not be a problem. EVs are suitable for balancing the grid and only load when there’s capacity in the grid. The marginal CO2-emmition of electricity produced for electric cars may in a coal-fired power plant may be lower than the like for other purposes. The reason is that the high flexibility in the charging stations. Energy conversion efficiency in coal-fired power plants are lower in low demand periods. Charging EVs when the demand is low may increase the energy conversion efficiency and thus lower the marginal CO2-emmition.

  • Ventilation required is probably for lead acid batteries like he said but not because of hydrogen buildup, though that is a hazard. It is probably for the possibility of production of hydrogen sulfide gas, which in my experience is always produced in some quantity when charging sets of lead acid batteries, thus ventilation is required unless you want to replace a lot of batteries. This isn't just for the health of the person using the charger; it is also to prevent corrosion of the internal components.

  • It is not smart to keep the old crap design that made old cars old. Lugging around a gigantically heavy lead acid battery is super dumb, it is much better to use only one type of battery and deliver all the voltages from there. A 24 volt network would probably work nice for the lights. You need 5 volts or less anyway for the computer that runs the whole car. I guess you can notice the difference of old car designs and the new "software defined car" where everything is controlled by software, the way that Teslas work. It allows constant improvements to everything, down to the electric motors.

  • 70% of electricity is generated by burning coal. Why someone feels "smug" about driving a coal burner is beyond me. Electric cars are not green because electricity is not green. With thousands of cars placing incredible new demand on the already maxed-out power grid EV owners may feel slightly less "smug" trying to charge their POS during a blackout stranded on the 405 with their dick in one hand and the SAEJ1772 in the other

  • It sounds like we have all the communication we need for load sharing. The charging station gets a littler smarter, hooking up to the other charging stations, and knowing how much current they have available. If you have 40 amps available and 4 charging stations, it seems obvious to me. Plug one car in, offer 40 amps. A second car gets plugged in, order the car to stop, and now frequency signal 20 amps to each car. Plug a third or fourth car in, offer 10 amps to each car. If the cars are working to the spec, 40 amps should never be exceeded. If a car finishes charging, cut it off and reallocate the current. We don't need the stations to talk to cars any more than the standard already allows. If we need 8 stations for that 40 amps, just have a maximum number that can charge at a time. 4 cars charge at 10 amps, 4 wait for their contactors to close.

  • Oh man again with this?.. Alec @Technology Connections .. Let's not even start with the fact, that where you see a car, I see a mountain of wasted (very scarce) lithium.. and a mountain of cell phones, laptops, and other equipment that really need Lithium. And that in the not too distant future they will no longer have it because we are dumping tons of it on this nonsense. (but Ramdileo you can RECYCLED IT) .. yes part of it.. and you use "Petroleum" and its derivatives for do that.. and then you get back a big chunk of the pollution that you saved using those batteries.. (you have the other part in the production and use of the device) laws of physics my friend... But .. Let's talk about something else "electric production.. less than efficient??!!" yea it is right? it sucks.. But do you really think that if is there a more efficient way.. or cheaper.. those filthy greedy old men.. Mr. Burns kind of disgusting dude... if is there really a better way to scratch a measly single penny .. they wouldn't use it?? (But Ramdileo.. you you can throw a SOLAR PANEL in the middle of nowhere and it will run forever) Of course not!!! (But Ramdileo.. those who are in the satellites WORK FOREVER) yes but they are in an environment of -250 degrees.. and where nothing touches them.... here you have high temperature.. you have pressure.. you have sand.. you have wind.. you have rain.. you have birds that shit on them... and etc etc etc etc... Aaaand because solar panel's are so highly inefficient at their task.. is not even worth the resources spent on its maintenance... ADD to that the resources spent on his own production (again scarce materials in comparison with other methods) ... and ADD everything else you need around them to make them work... And you see why we still use the Hoover Dam...
